Did you notice the car get sluggish under acceleration because of the bigger wheels. I just put 19s on my 520d from 17s and it kinda feels it lost some of its low end torque. Wife says otherwise so maybe I am just imagining it

Thanks, not sure if or when i will be lowering it. Not long before the damn snow here in Norway Also we have one hell of a speedbump on a private road very short and very high cant do more than 3-4 km/h over it. Will try to take some more pictures where you can see how flush the wheels are maybe tomorrow or saturday.

The color is Carbon Black, atleast thats what it's called in Europe. I think it's only available with the M-sport exterior package.

Can't say that i've noticed this. Not sure how much the std 18" rims weigh, but the BBS CH-R weight is about 13-14 kg i think. The ride is much smoother now with the PSS tires than with the runflats. The car feels alot more stable on the road. Even the road markings made the care unstable when changing lanes with the runflats, also had a slight vibration when driving about 110-120 km/h (could feel it in the seatback) All this is gone with the new wheels and tires. Now the car feels and drives amazing.

EDIT: This is the weights for OEM 18" and BBS CH-R 20"

Style 350M
8x18 Front 245/45R18 ET 30 11,40 kg

9x18 Rear 275/40R18 ET 44 11,90 kg

BBS CH-R
9x20 Front 255/35R20 ET 29 12,6 kg

10,5 Rear 295/30R20 ET 35 13,21 kg

so 1,2 kg more in front and 1,3 kg more on the rear wheel. Not a whole lot more weight but of course there is the bigger tire too so maybe 2 kg more on each wheel.
But i think maybe its possible to notice it between 17" and 19". Could be more difference in weigt there than on my wheels.

If you want to keep the EDC, you need to drop it by just changing the springs.
But all the pics I've seen of such drops, it looks like a mild drop of 2-3cm. So I doubt it wil get you into trouble in snow or over speedbumps.

Coilovers will change the EDC dampers too, so that function won't work anymore.

The edge og the tires on front wheels are about 3-4 millimeters outside of the fenders and rear wheels 4-5millimeter outside when it stands level. Looks quite agressive. It will probably be absolutely flush with the fenders if the car is lowered about 2-3 cm like you suggested. Now the rims are flush.

Lads, can I clarify your terminology cos I want to drop my F10 535 and I think we might refer to things a little differently here in Oz. What you refer to as Dampers we might call Shock Absorbers (??) and what you call Coilovers we might call Springs (??). Is that right or are you referring to something else ? My 535 is Standard (i.e. not an M Sport), it's not an XDrive, and doesn't have Adaptive Drive (i.e. EDC or Comfort). From what I have read from this forum, the ACS (AC Schnitzer) might give me the best effect (drop without loss of ride quality) but I'm unsure if I need to do anything else and would appreciate your guidance .
